Description
Technical field
The present invention relates to field of medical, be specifically related to a kind of VVS therapeutic instrument.
Background technology
VVS, refer to that various stimulations are by vagus nerve mediation reflection, cause the little vasodilation of internal organs and muscle and bradycardia, the peripheral blood rostrum is so expanded, the venous backflow heart reduces, make heart that the reflex action of accelerating and strengthening contraction be arranged, some people can be because excessively exciting vagus nerve and parasympathetic nervous, and then cause that heart beating is slowed down suddenly, the peripheral blood enlargement of pipe, the result causes blood pressure reduction, brain anoxia, show as arterial hypotension with of short duration loss of consciousness, can recover voluntarily, and a kind of syndrome of impassivity location sign.
VVS belongs to neural reflex and faints that (vasovagal syncope VVS), is the modal type of fainting, and it is reported that its prevalence is about 20-40%.There is clinical intractable and high incidence in vasovagol syncope.
At present, the method for the treatment of VVS roughly is divided into two kinds: (1) Drug therapy; (2) implant a pacemaker.
Take at present the method for Drug therapy mostly, people had proposed therapeutic schemes such as " beta-blocker, norpace (disopyramide), heart heartstarts " according to the VVS genesis mechanism in the past, but its curative effect differs.Mostly the proposition of these schemes is still to lack convictive clinical test results on the basis of the experience that is based upon and reasoning, thus the safety of said medicine and effectiveness still be difficult to determine, and take medicine for a long time various complication arranged.The patient takes gutron (pressor agent) for a long time, may cause feeling sick scalp itch, side effect such as hypertension.The patient takes beta-blocker such as metoprolol for a long time symptoms such as weak, bradycardia may occur.
Permanent cardiac pacemaker is installed can be controlled the outbreak that VVS patient faints, but expensive and belong to the invasive procedures treatment is arranged because of it, have certain risk, be difficult to obtain patient's acceptance.
The physical exercise method of bending and stretching of employing arm and shank can be prevented and treated VVS patient to a certain extent and be had a syncopal attack, but this method is not suitable for the patient who does not have the symptom in early stage.

Described air pump is for providing treatment required compressed air, the compressed air that air pump produces, by three electric control valves, in three air bags for the treatment of trousers, inflate successively by certain cycle, limbs are produced the segmental extruding of from bottom to top successive generation, the effect that causes massage and push promotes the blood of lower limb to be back to heart, thereby prevents the generation of VVS.Three electric control valves are realized " advance, protect, arrange " function by the program work of setting.Described pressure regulator valve is frame for movement, aperture by the manual adjustments valve obtains different pressure, and gas pressure is stabilized in required treatment pressure limit, the online adjusting of big I for the treatment of pressure, and show in real time by accurate pointer pressure, satisfy in the therapeutic process needs to the pressure increase and decrease.The treatment pressure of design can be regulated by pressure regulator valve, is up to 30Kpa.Take into account different human body simultaneously to the tolerance level for the treatment of pressure for the needs that satisfy treatment, 10-15KPa is more satisfactory treatment pressure, is fit to treatment at ordinary times and uses.When treatment pressure is set to 20KPa, be fit to 30-60 minute stage treatment; When treatment pressure was set to 25-30KPa, treatment time should be controlled in 30 minutes.Inflated by air pump and electric control valve from bottom to up inferior ordered pair three chambeies when wearing band, finish pressures cycle after making three chambeies reach the pressure of setting, position (two lower limb) blood flow rate is worn in raising; Three air bags by the treatment trousers apply circulation circumferential pressure and gradient force to shank, just can guarantee that blood flow rate is stabilized in a higher level, thus mobile more blood, effectively the alluvial blood of the two lower limb of removing.
Described main frame is provided with two kinds for the treatment of patterns, and described main frame carries out the switching of two kinds for the treatment of patterns by mode selector switch, and shows the treatment pattern of choosing by the dual-colored LED display lamp.
The treatment pattern:
One: 3 electric control valve of pattern is opened (inflate simultaneously in three chambeies) simultaneously, in three cavitys for the treatment of trousers, be inflated to setting treatment pressure (inflationtime 30 seconds simultaneously, the blowing pressure 0-30KPa, the online adjusting of available high accuracy pressure regulator valve) also keeps (30 seconds retention times), aerofluxus then (evacuation time 15 seconds).Follow three cavity repeated inflation, maintenance, exhaust process, so circulation is carried out, and arrives up to the intervalometer timing, and machine stops, the treatment end.
Two: 3 electric control valves of pattern are successively opened, and are inflated to the pressure (inflationtime 30 seconds, the blowing pressure 0-30KPa can onlinely regulate) of setting and keep (i.e. not aerofluxus) at first for the ankle chamber for the treatment of trousers; Be inflated to the pressure (inflationtime 30 seconds, the blowing pressure 0-30KPa can onlinely regulate) of setting and keep (i.e. not aerofluxus) then for the shank chamber for the treatment of trousers; Be inflated to the pressure (inflationtime 30 seconds, the blowing pressure 0-30KPa can onlinely regulate) of setting at last the thigh chamber for the treatment of trousers.Three cavitys keep the blowing pressure to the time of setting (30 seconds retention times) then, the aerofluxus (evacuation time 15 seconds) simultaneously of last three cavitys.Then repeat said process, so circulation is carried out, and arrives up to the intervalometer timing, and machine stops, and treatment finishes.
Regularly start/stop: adopting 90 minutes mechanical timer of the longest timing (time length scalable), be installed in mechanical timer on the therapeutic instrument and cooperate software program realize the fainting timing of therapeutic instrument to start and stop.
Referring to Figure 10, the software control procedure of single-chip microcomputer mainly shows that by: key scan (model selection) subprogram, LED (pattern demonstrations) subprogram, the subprogram for the treatment of pattern, time delay subroutine, definition status detection subprogram form.
The program operating procedure:
Whether 1, program begins to do earlier key scan, detect treatment model selection button and pressed down;
If 2 treatment model selection buttons are pressed down, time-delay a period of time, do the elimination dithering process, avoid maloperation, determine that button is pressed after, enter the treatment pattern of choosing, LED light is bright accordingly;
3 then detect the duty (setting the treatment cycle time by intervalometer) of intervalometer, if intervalometer starts, and the treatment pattern (if intervalometer does not start, machine is in halted state) that system's operation is chosen;
4, meeting in service constantly detects the intervalometer state, if intervalometer is in starting state always, program just circulation is always carried out the treatment pattern of choosing;
5, when detecting intervalometer and stop, buzzer sends prompt tone, and machine quits work.
